HOW TO: Cheap Incubator Fan!

[Nate]

Good stuff...

How do you know the fan won't go out because of too much power?

How much power does that charger put out? and what is the minimum and maximum amount of power that fan can handle?

I'd hate for that fan to mess up with eggs...i think it's a great idea and I'll probably do it...i just want to clarify some things

on the back of the charger it says the output voltage which in this case is 5.9v, the fan starts at 6v and runs best/fastest at 12v. Im actually underpowering it but it runs. If you can find a 12 volt charger it will run at its best

awesome thanks!

if you want to get one from radio shack if you cant find one at your house, the exact one should say
input: 120VAC
output: 12VDC

Good work. I think I beat you to this one.

No hard feelings.

The other thing I've noticed when I make these is that different fans have narrower margins for voltage and amps. I have a few 5v fans running off a 3v. DC transformer, but I just bought a bunch of 12v 1500mA fans to build incubators and I got 12v 500mA transformers to power them and they don't even start up. I'd imaging that some fans will run but quickly fail if you use the right voltage but over do it with the amps. Something to watch out for. I think you should be safe undershooting the voltage by 10%-20% if you don't want the motor to run at full power, as long as the amps are right on.

I hate you! j/k lol

Sorry man. I don't want people paying $13 for your transformers when they could get them for $3. Especially once I found out the 12v 500 mA ones wont power my 12v fans.

thanks for this ive found an old adaptor that is working a treat as we speak.

May i post this to my site?

I know the last post here was almost a year ago but I need your help. I have made a poultry incubator. And am now trying to make it a moving air incubator. I have two fans I removed from old computers that were working when I removed them. I have tons of those old chargers. The two fans I have are:
Quiettek - Brushless DC12V 0.23A
FU DC Fan Brushless DC 12V 0.15A

The adaptors/chargers I have are:
Unisonic 120V AC 7W
Thomson 120V AC 5W (I tried both fans using this but nothing)
Panasonic 120V AC 4W

The Unisonic and Panaonic both still have the plugs on them before I cut off the plugs I was wondering if anyone can tell me; why the Thomson didn't power the fans and which of the other two would be the best to use?

Also what about connecting two fans together at opposite ends of the incubator to create a better flow?


Any help would be greatly appreciated.

Thanks
